in Polishing-Wheels, of which the following is a specification, containing a full, clear, and exact description, reference being bad to the accompanying drawings, forming a parthereof.

My invention relates to an improved polishing-wheel, and. has particular relation to that 'class of polishing-wheels inwhich the polishing is effected by means ofstrips of wheel embracmg a side view of emery-paper and \the like removably mounted upon the periphery of a driven wheel.

, In the drawings, Figure 1 isaperspectiv'e view of a wheel embodying my invention. Fig. 2 is an enlarged view of aportion of such the clamping device employed. Fig. 3 is a perspective view of the portion of the wheel shown in Fig. 2. Fig. 4 is a transverse sectional view of the same taken along th line 44 in Fig. 2. Fig. 5 is a perspective view of the clamping-arm.

In the drawings, the strip of polishing mamounted upon the face of the flat face bandwheel 2. a In practice in the art to which my invention relates such band-wheels are usually made of metal, and in measurably resilient polishing-surface which will protect the article being polished from injury during the operation of polishing I have provided the strip like material and which is glued or otherwise affixed upon the outer faceof the rim 3 to serve as a cushion for'the polishing-strip 1.

It is indispensable to the successful opera tion of a polishing-wheel that the polishingprovided the rim 1 is placed in "surface should be substantially continuous, seamless, and unbroken. To that end I have 3 with the outwardly-projecting flanges 5 and 6, which are of aheight equal to the'thickn'ess of the strip 4 and over which-the strip 1 is to be tightly drawn, as indicated in the. drawings. When the-strip position upon .the wheel, its

' ends pass inwardly between theflanges 5 and 6 through the slot 7 and 'into the opening 8. The

ends of the strip 1 are then tightened by being of the pin 12. vided with the jaw 13,:which is adapted to shown in Fig. 2, when order to provide a 4, which is of felt or.

drawn into aroll, which roll is indicated by the numeral 9 in Fig. 1. The winding of this roll is best accomplished by means of'the ordinary split key, which is well known in the art,

and is therefore not shown in the drawings; The strip 1 'is-then locked in position bystraightening the clamping-arm 10, which is a flexible double arm .pivotally mounted in the wheel 2 by means .of the pin 11, the arm 10 being broken about midway its length and the parts pivotally connected together by means The end of the arm, 10 is prothrust the end of the stripl into the corresponding recess 14' in the member 15, with which the flange 6 is shown in the drawings In order to permit the inas being integral.

troduction of the ends of the strip 1 to the opening 8, the arm 10 is forced to an unlocked 6 position, as shown in Fig. 3, the pin 10 being thrown toward the center of the wheel 2 in the slot 16. When the strip 1 has been tightened, the arm 10 is straightened to the position I the pressure of the jaw 13 against the recess 14 will hold the strip 1 securely in place, arm 10 will bereversed when it is desired to remove the strip 1 from the wheel. I claim' p 1. In a polishing-wheel: the wheel 2 having an opening 8 and a slot 16; the rim 3 upon the wheel and having the transverse slot 7 communicating-with the opening 8; the flanges 5 and 6 extending outwardly from'the rim, one upon each side of the slot 7; the cushion 4 upon the outer face of the rim and butting against the flanges 5 and 6; the clamping member 15 upon one side of the slot 16 in a radial line with the flange 6, and having the angular recess 14 in its clamping-face; the strip 1 of polishing material upon the cushion with its ends extending over the flanges 5 and 6 and through the slot 7 "nto the opening 8; theclamping-arm 10 having a clamping-face in oposition to-the recess 14; said clamping-arm being connected to the wheel by a toggleejoint, so as to grip the polishing material in the recess 14; substantially as specified.
